What is a nonlinear graph?

Back

A nonlinear graph is a graph that does not form a straight line when plotted. It represents relationships that are not proportional.

What is the equation of a line in slope-intercept form?

Back

The equation of a line in slope-intercept form is y = mx + b, where m is the slope and b is the y-intercept.

What does it mean for a relationship to be proportional?

Back

A proportional relationship means that two quantities maintain a constant ratio, and the graph of the relationship passes through the origin.

How do you find the unit rate from a proportional relationship?

Back

The unit rate is found by dividing the total quantity by the number of units, giving the amount per one unit.

What is the slope of the line represented by the equation y = 2x + 6?

Back

The slope of the line is 2, indicating that for every 1 unit increase in x, y increases by 2 units.

What does it mean if a graph is not a function?

Back

A graph is not a function if any vertical line drawn through the graph intersects it at more than one point.

Front

What is the difference between linear and nonlinear equations?

Back

Linear equations produce straight-line graphs, while nonlinear equations produce curves or other shapes.

How can you determine if a graph is proportional or non-proportional?

Back

A graph is proportional if it passes through the origin (0,0) and has a constant slope.

What is the equation for a proportional relationship?

Back

The equation for a proportional relationship can be expressed as y = kx, where k is the constant of proportionality.
